24 For Romanian climate conditions Minimum passive house standard (PHPP tool) Special conditions for summer season climate change results 2 seasons spring SUMMER + autum- WINTER (solar protection & design of thermal envelope & utilities ) Easy to transform in Near Zero Energy Building or ZEB Plus Energy Buildings Or ACTIVE BUILDINGS 24

25 Living and working in Buildings with a good energy efficiency balance (more than 10 years) Forget about energy bills Zero energy buildings Investition 25

26 For example, about half of the energy consumed in Europe goes on heating and cooling of buildings and for industrial applications. Satisfying this demand by solar thermal systems is one proven and cost-effective technology solution. For renewable energy, a new era that remove barriers and mobilise investment is now in run. Energy needs must be included from the beginning on the planning stage. 26

27 Wright now and not in the future, buildings design need a complete reinvention of energy consumption, conservation and production. A comprehensive holistic energy efficiency design for cities and buildings. Extreme energy efficiency is the base for a green, clean, safe and renewable energy, easily accessible for those who need it. Correct design and construction can contribute to dramatically decrease energy consumption and CO2 emissions of dwellings. 27

28 ENVIRONMENTAL FRIENDLY GREEN ECOLOGICAL USING ENERGY FROM RENEWABLE SOURCES SUSTAINABLE DEVELOPMENT means also Healty planet and Healthy people 28
